Add your DIVX file
Drop one or more .divx files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
DIVX to 3GP
Pulling the soundtrack out of a .divx video into .3gp audio keeps what you can hear and drops the picture entirely. Free, private, and validated — the file never leaves your browser.

Pulling the soundtrack out of a .divx video into .3gp audio keeps what you can hear and drops the picture entirely. A .divx file is video packaged for the DivX ecosystem: an AVI-derived container carrying MPEG-4 Part 2 video compressed with the DivX codec. The extension appeared on rips and downloads throughout the 2000s, when DivX certification logos on DVD players promised these files would play from burned discs.
A .3gp file is a lightweight container defined by the 3GPP standards body for video recorded and shared on mobile phones. It packs low-bitrate video and compressed speech with minimal overhead, which made .3gp the format of MMS messages and early camera phones. For this route the practical draw is extremely small files by design and structural kinship with MP4 makes conversion quick — balanced against picture quality is poor by any modern standard, which is worth knowing before you commit a large batch.
Why convert DIVX to 3GP?
The usual reason to take .3gp audio out of a .divx file is that only the sound matters — a talk, interview, song, or podcast segment. Keeping the video stream would waste storage, and a dedicated audio file is easier to trim, tag, and play. On the source side, obsolete next to H.264 and H.265, needing more bits for the same quality; on the target side, the payoff is extremely small files by design, which is exactly what you want for recovering videos from old feature phones and their memory cards.
DIVX vs 3GP at a glance
| Aspect | DivX video (.divx) | 3GPP video (.3gp) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | aVI-compatible RIFF layout extended by the DivX Media Format with menus, chapters, and XSUB bitmap subtitles | iSO base media structure like MP4, but with a deliberately restricted codec list |
| Strongest at | playing movie archives from the 2000s downloading era | recovering videos from old feature phones and their memory cards |
| Weak spot | obsolete next to H.264 and H.265, needing more bits for the same quality | picture quality is poor by any modern standard |
| Metadata | inherits RIFF INFO tags from AVI, plus DivX-specific chapter and menu structures in Media Format files | a small set of 3GPP-defined asset atoms for title, author, and location exists, though most recording phones never wrote them |
Pick 3GP as the output
Select .3gp in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if 3GP is selectable, the route is real and validated.
Convert on your device
Press Convert. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid 3GP file. Outputs keep the original filename with the .3gp extension.
DIVX to 3GP questions, answered
Will converting DIVX to 3GP lose quality?
Since divx is container-oriented and 3gp is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .3gp itself requires.
Is it private to convert DIVX files here?
Yes — the .divx file is processed inside your browser tab and never uploaded. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded. Close the tab and the file is gone from memory.
Where will the 3GP file work?
Android still opens most .3gp files, and desktop players such as VLC handle them, but iOS and web browsers generally do not. Because the codecs inside are dated, converting to MP4 with AAC audio is the standard path to modern playback.
Will the 3GP file be bigger or smaller than my DIVX?
Much smaller — the video stream is usually 80–95% of a .divx file's weight, and it is discarded entirely. The remaining audio is re-encoded at the bitrate implied by your quality setting.
What happens to the metadata in my DIVX file?
This converter strips container metadata deliberately (the FFmpeg command runs with metadata mapping disabled) so exported files do not leak recording details. In the source, inherits RIFF INFO tags from AVI, plus DivX-specific chapter and menu structures in Media Format files; none of it is transmitted anywhere because the file never leaves your browser.
Can I convert 3GP back to DIVX?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .divx → .3gp → .divx is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
